Android devices captured 22 percent of global tablet shipments in
the three months to Dec. 31, up from 2.3 percent in the preceding
quarter, the Boston-based researcher said in a statement today.
The iPad accounted for 75 percent of shipments in the period, down
from about 95 percent, it said.

That’s the original 7-inch Galaxy Tab, the one that ran the non-tablet Android 2.3. And these sort of reports are what led to the whole sell-in/sell-out thing with Samsung later that month. So it seems pretty clear that today’s numbers from Strategy Analytics only reflect how many tablets are being put on the market, not how many are actually being sold to customers.
